AROUND ten girls were reportedly pricked by a man with a syringe during a French musical festival.

The incident is said to have unfolded in Metz on Friday, when over 50,000 flocked to celebrate World Music Day, Le Républicain Lorrain reports.

The girls – most reportedly minors – were targeted by one or more people at around 10pm, according to the local outlet.

The alleged attacks happened between two popular spots in the city centre, Place de la République and Place Saint-Jacques.

Firefighters at the event quickly tended to the girls, who were then rushed to hospital “for analysis”, according to Metz mayor François Grosdidier.

A man was arrested by local cops in connection with the incidents.

He was taken to the police station to be interviewed.

Grosdidier estimated that a crowd of 50,000 packed the city centre, adding: “It’s Saturday night and it’s still hot… There are a lot of people, people everywhere, in all the city centre streets.”

Police remained on duty throughout the night following the incident.

It comes as a school girl was stabbed to death by a 15-year-old student who went on a knife rampage at a school in the French city of Nantes.

The attacker, wearing black clothing and a balaclava, also stabbed three other students who were rushed to hospital.

When armed cops arrived at the scene, the attacker reportedly shouted “shoot me in the head” before being handcuffed and taken away.

The suspect was named as Justin P. by French newspaper Le Parisien.

Just hours earlier, an anonymous email is said to have gone around the school speaking of a “revolt”.

The manifesto, reportedly seen by Le Parisien, spoke about eco issues.

Meanwhile, a teaching assistant was stabbed to death by a teenage student over a week ago.

The 31-year-old was stabbed several times outside the Françoise Dolto school, in north-east France. 

She tragically died in hospital as a result of her injuries. 

A 14-year-old pupil was arrested on suspicion of fatally stabbing the teacher who was leading a bag search outside the school at the time.

The victim – identified only as Melanie G – was mum to a four-year-old boy and has been described by locals as “adorable” with a “caring nature”.
